✓ Traumatic intracranial aneurysms are rare complications of closed and penetrating head injuries and may also be related to a variety of neurosurgical procedures. The primary goals in the treatment of patients harboring these lesions are early identification and intervention to prevent bleeding. Traumatic aneurysms are fragile, prone to rupture, and represent a challenging subset of vascular lesions for either surgery or endovascular therapy. Surgical approaches to aneurysms located at the pericallosal arteries are associated with higher rates of morbidity and mortality than approaches to other supratentorial aneurysms. Current endovascular treatment most often involves occlusion of the parent artery with the potential of added morbidity. The authors present their experience in the endovascular management of traumatic and iatrogenic aneurysms of the pericallosal artery achieved by primary coil embolization with parent vessel preservation. For patients harboring traumatic pericallosal aneurysms with favorable anatomical characteristics, in which the morbidity caused by parent vessel occlusion is not acceptable, endosaccular coil placement may be a valuable option.
